In the operation of pulling the container 50 forward and pushing the container 50 into a predetermined position, the convex portion 62 remains in the groove 70. The groove 70 forms a bottom surface continuous with the rear rail surface 65, and the width of the bottom corresponding to the lower end of the convex portion 62 is the same as or slightly wider than the thickness of the convex portion 62, and the left and right side walls of the groove 70 Forms an inclined surface extending outward from the bottom of the groove 70. For this reason, the horizontal shaking of the container 50 is limited by the left and right walls 66A and 66B of the groove 70, and the sliding of the container 50 in the front-rear direction can be performed smoothly. Further, there is little resistance when the container 50 swings in the left-right direction and the convex part 62 comes into contact with the left and right walls of the groove 70, and even if the convex part 62 climbs the left and right walls of the groove 70, it always descends to a predetermined position. Since it returns, the container 50 can always hold a predetermined position. Further, when the container 50 is housed in the specific low temperature chamber 9 due to the inclination of the left and right walls of the groove 70, the operation of fitting the convex portion 62 into the groove 70 is easy.

On the lower surface of the right end of the support portion 55, a downward convex portion 62A extending horizontally in the front-rear direction is formed.
[0025]
In the front portion of the rail portion 60, a pair of left and right walls 66A and 66B integrally formed with the rail portion 60 are formed integrally with the rail portion 60 between the front and rear grooves 70A. The bottom surface of the groove 70 </ b> A is flush with the rail surface 65 on the top surface of the rail portion 60. The pair of left and right walls 66A and 66B may have the same length, but the right wall 66B is formed long in the front-rear direction of the rail portion 60. The groove 70A has a width that fits the ridge 62A so as to be slidable in the front-rear direction and restricts movement of the ridge 62A in the left-right direction. For this reason, the width of the bottom of the groove 70A is the same as or slightly wider than the left and right widths of the lower end of the ridge 62A, and the left and right side walls of the groove 70 form an inclined surface extending outward from the bottom of the groove 70A. ing.
[0026]
As an example, the left and right thickness of the protruding portion 62A is 4.5 mm, the width of the bottom surface of the groove 70A is 4.5 mm, and the height of the left and right walls 66A and 66B from the bottom surface of the groove 70A is 3 mm. The left and right walls extend from the bottom surface of the groove 70A to the height of the left and right walls 66A and 66B with an inclination of 45 °. For this reason, there is little contact resistance with convex part 62A, and even if container 50 shakes right and left and convex part 62A climbs this inclination, it will return to the bottom of groove 70A easily. The convex portion 62A of the support portion 55 and the rail portion 60 constitute a support device on the right side of the container 50. When the container 50 is set in the specific low temperature chamber 9, the rear end portion of the convex portion 62 makes it easy to insert the convex portion 62 </ b> A into the groove 70 </ b> A by the slope 62 </ b> B with the corners cut off. The same effect can be obtained even when the width of the bottom surface of the groove 70 is 4.5 mm to 5.5 mm.
[0027]
With this configuration, the convex portion 62A slides on the rail surface 65 on the upper surface of the rail portion 60 while entering the groove 70A. Restricting the container 50 to be pulled out forward is achieved by a locking projection 73 formed on the lower surface of the support 53 contacting the support 58.
[0028]
As described above, the present invention limits left and right shaking by a combination of the convex portion 62 or 62A and the groove 70 or 70A. However, the present invention is not limited to the above embodiment, and various forms of refrigerators and thermostats, The present invention can be applied to a warm storage, a freezer, and the like, and various modifications can be considered without departing from the technical scope of the present invention, and includes various embodiments related thereto.
